Harmful deposits and varnish build-up-resulting from worn-out, oxidized brake fluid-are apparent on this brake master cylinder piston assembly.

• Remove contaminated fluid from the brake lines and master cylinder.

Replace the old fluid with High Temp Formula Heavy Duty DOT 3 or DOT 4 Brake Fluid, which is domoisturized to prevent corrosion.

The entire brake system will be inspected for leaks, master cylinder corrosion, worn pneumatic parts, harmful varnish build-up, broken or rusted bleeder valves, worn rotors and drums, and air in the brake lines.
